Image forming apparatus, control method, and control program in which a magnitude of a current to flow in a paper sheet at the time of toner image transfer can be set

Abstract

An image forming apparatus includes: an image carrier configured to carry a toner image; a transfer member configured to transfer the toner image onto a transfer target member by applying a transfer voltage of the opposite polarity of the polarity of the toner image to the transfer target member, the transfer member being in contact with the image carrier; an accepting unit configured to accept a setting for changing a preset current range to a new current range, the preset current range being defined by one of a lower limit of a current flowing in the transfer target member and an upper limit of the current; a sensing unit configured to sense a magnitude of the current flowing in the transfer target member; and a control device configured to control the transfer voltage so that the magnitude of the sensed current falls within the new current range.

Description

[0001]The entire disclosure of Japanese Patent Application No. 2015-248686 filed on Dec. 21, 2015 including description, claims, drawings, and abstract are incorporated herein by reference in its entirety.BACKGROUND OF THE INVENTION[0002]Field of the Invention[0003]The present disclosure relates to control of an image forming apparatus, and more particularly, relates to control of electrophotographic image forming apparatus.[0004]Description of the Related Art[0005]Electrophotographic image forming apparatuses are widely used today. An electrophotographic image forming apparatus performs a printing process that includes a process of forming a toner image on an image carrier such as a photosensitive member or an intermediate transfer member, a process of transferring the toner image from the image carrier onto a paper sheet, and a process of fixing the toner image to the paper sheet.[0006]The transfer of a toner image from an image carrier onto a paper sheet is performed by a transfe...

AI Technical Summary

Benefits of technology

The patent describes how to transfer toner images from one belt to paper. The technical effect is to improve the transfer process and produce higher quality images.

Problems solved by technology

With such changes, the transfer voltage to be applied to the transfer member might also change, and cause a decrease in print quality.

As a result, current does not smoothly flow in paper sheets.

Furthermore, in a case where printing is performed on a paper sheet with an unexpectedly high resistance value (such as a paper sheet with poor quality), current does not smoothly flow in the paper sheet.
